Right, this was a thing I was wanting to do for a while, but kept forgetting and not having the motivation to do (thanks work for making me work 60 hour weeks every week)... As the title says these are some of my predictions for E3, and a couple hopes, in no particular order:

-New Smash Brothers character, most likely from a new IP in the series
-Zelda 35th anniversary celebration, with possibly a "Zelda All-Stars" game
-Final Fantasy 7 Remake game 2 announcement
-Confirmation or Denial of "Switch Pro"
-Breath of the Wild 2 release date
-New Kingdom Hearts game, or one tied to it, if not called KH
-More info on Final Fantasy 14: Endwalker, even though the Fan Festival was last month
Honorable Mention: Dragon Quest 35th anniversary celebration, since I originally predicted that before I found out they already did it! (Super Hype for the DQ3 remake btw, love that game so much)

and I'll close it off with my hope, a big one.... Golden Sun 20th anniversary celebration, either a new GS game, a remake of the GBA game(s), or a playable rep in SSBU (PLEASE NINTENDO! GIVE US GOLDEN SUN THINGS!!)
